bumpers and covers Reply #1 – February 15, 2011, 06:28:40 AM It's a totally differant shape? I wouldn't think so. Do you need an 83-86 bumper? I have several Quote Selected
bumpers and covers Reply #2 – February 15, 2011, 12:24:56 PM Looking to trim some weight without impacting (nyuk nyuk) safety. I blame fordguy545 and gumby for this thread. After seeing fordguy545's trimmed bumper, it got me to thinking about using pre-preg CF *as a reinforcement. Trim a factory metal (or fiberglass) bumper of as much material possible, lay the pre-preg, bag and cure it.* http://tinyurl.com/46kcwht Quote Selected
bumpers and covers Reply #3 – February 15, 2011, 05:08:13 PM If you are gonna be tpuppies it, and already planning to lay the pre-preg CF, I'm sure you could make the 87-88 bumper fit nicely inside the early cover. The 87-88 bumper would make a much lighter base to begin with, and likely a fairly easy substrate to bond the CF onto.I already have a few guys who blame me for certain car hobby related choices they have made; get in line :nkhk: Quote Selected
Another thought: Reply #4 – February 20, 2011, 08:09:07 AM I was considering a CF or fiberglass hood but don't see that as a viable choice now. fordguy545 shed a few pounds by removing part of the underside support frame of the hood and trunk. Would a sheet of pre-preg laid on the underside restore the some or all of the stiffness? It would be easy to prep the surface then bag and cure it. Quote Selected
bumpers and covers Reply #5 – February 20, 2011, 11:32:47 AM Workin from what I see on our racecars that have CF bodies, rather than adding thickness to the entire panel for rigidity there are patches added only to the specific areas that require it. I would assume the same would hold true on the underside of a sheet metal hood to some extent. Quote Selected
bumpers and covers Reply #6 – February 20, 2011, 12:56:54 PM Bumper question - are the bumpers straight bolt-in swaps with regard to mounting (not counting bumper cover)?Lid questions - I ASSume the loss of rigidity is torsional and not surface deflection? If one were to chop the underside like 545 did, then lay a sheet of CF everywhere there wasn't the reinforcement, would that work like the mods on the race cars? Or would a third layer of another material need to be added, eg foam core? Quote Selected

hmm, could there be another purpose here? Reply #13 – February 26, 2011, 06:07:00 PM Something besides weight loss? Quote Selected
one more thing Reply #14 – February 26, 2011, 06:09:41 PM Thishiznit the floor as the rear bumper came off the car.Was Ford using punch cards at the time? Quote Selected
